The Brooklyn Park City Council reviewed preliminary layout designs for the Highway 169 and 101st Avenue
interchange project on Feb. 27. The proposed layout, a folded diamond interchange, is part of the second phase of a corridor study prepared by SRF Consulting Group.
The proposed construction area runs from Xylon Avenue to Jefferson Highway. The project includes a four-lane bridge taking 101st Avenue over Highway 169 and auxiliary lanes on Highway 169. Projected costs are approximately $31 million, based on 2016 dollar values.
Approximately 12.9 acres of right-of-way would need to be purchased for the project, with approximately 3.3 of those acres owned by Three Rivers Park District.
Project funding would need to come from multiple sources. At this point in the project, federal funding has not been acquired.
“One of the things we are looking closely at, there was a recent federal funding solicitation that comes out through Met Council,” said Kevin Jullie, SRF engineer. “We applied for that. I think we’re right on the bubble. We’re kind of holding our breath hoping that comes through for us.”
The city applied for the maximum funding amount from the solicitation, which is $7 million.
State funding from the Department of Employment and Economic Development could potentially provide $7-10 million for the project, said Jeff Holstein, city transportation engineer.
City Manager Jay Stroebel said funding could potentially come from bonding bills in the state Legislature in 2018. The city would hope for $11-13 million in bond funding, he said.
In some cases, a local funding match would likely be expected, Stroebel added.
Mayor Jeff Lunde said when past road projects have received funding, it was in part because the planning stage was completed, and projects were otherwise ready for construction. He said it is important for the city to continue moving forward with planning so it is prepared when funding sources become available.
Construction of the interchange is slated to occur at approximately the same time as Blue Line LRT construction in the area.
The interchange would not impact the Rush Creek Regional Trail or the pedestrian bridge over Highway 169.
Construction would impact approximately 6.8 acres of aquatic resource and wetland impacts.
Holstein said a previous study has confirmed the need for the interchange, as growth in the area based on the city’s preferred land use is expected to bring 80,000 to 100,000 new trips per day to the corridor in coming years.
“Part of what we looked at was the local roadway network, particularly looking at Oak Grove Parkway with 101st Avenue, making sure they match in,” Jullie said.
Other roads are expected to be constructed in the area as part of the Blue Line Extension project, which plans to place the Oak Grove Station near the interchange. Jullie said SRF collaborated with the Blue Line project to determine the best placement of the interchange.
Jullie said the folded layout was selected in an effort to save space, as the Highway 610 and Highway 169 interchange does not leave room to the south of 101st Avenue.
“As part of our interchange project, there will be a lane coming off of the 610 ramps and connecting into our ramps on 101st,” he said.
While the bridge over Highway 169 will be four lanes wide, Jullie said they are still determining how many lanes would be needed between the bridge and Jefferson Highway.
For stormwater management, ponds and infiltration basins will be used throughout the project, Jullie said. Road noise levels for the area are projected to be similar before and after the project, he added.
MnDOT’s Cultural Resources Unit determined that no historic properties are affected by the project. Jullie said MnDOT’s Layout Review Committee is expected to approve final layouts this year.
The majority of the traffic on the interchange will be coming from the south on 169 or coming off of Highway 610, Holstein said.
Lunde said the council should plan a joint meeting with the Champlin City Council to discuss the details of upcoming projects and potential traffic impacts.
The project’s study advisory committee is comprised of members from MnDOT, Hennepin County Transportation and Transit, Met Council, Metro Transit, the cities of Maple Grove, Champlin and Osseo, Holstein, a study consultant from SRF Consulting and a Target Corporation representative.
